Abstract : Bars 20 mm thick hot rolled from degassed SAP-1 powder were rolled first at 450 degrees centigrade into plates 3 and 10 mm thick, and then cold rolled with a reduction of 50 or 85 percent without process annealing into sheets of the same thickness. The sheets after annealing at 600 degrees centigrade for 2 and 20 hr., at 640 degrees centigrade for 2 and 20 hr., and at 670 degrees centigrade for 2 min., 20 min., and 20 hr. were subjected to tensile tests at 20, 350, and 500 degrees centigrade at a rate of 5 mm/min with a holding time of 15 min at elevated temperatures.
